[Intel-gfx] [PATCH v2] drm/i915: Refer to GGTT VM consistently
Joonas Lahtinen
joonas.lahtinen at linux.intel.com
Wed Mar 23 13:18:31 UTC 2016
Refer to the GGTT VM consistently as "ggtt_vm" instead of just "ggtt",
"vm" or indirectly through other variables like "dev_priv->ggtt.base"
to avoid confusion with the i915_ggtt object itself and PPGTT VMs.
As a bonus gets rid of the long-standing i915_obj_to_ggtt vs.
i915_gem_obj_to_ggtt conflict, due to the other becoming
i915_obj_to_ggtt_vm!
v2:
- Added some more after grepping sources with Chris
